LUBBICATING DEVICE FOR INTERNAL-COMBUSTION ENGINES.

Application filed August 9,

- conveyed to a supply pipe by capillary action.

The nature and advantages of the invention will be better understoodwhen jthe following detail description is read inconnection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views and wherein:

Fi re 1 isa fragmentary view of a motor showing the application of theinvention.

Figure 2 is a sectional view through the supply tank.

Figure 3 is a sectional view on line 3-3 of Figure 2.

Figure-4 is a fragmentary view.of the tubular member arranged centrallyof said tank for the reception of the feltroll.

Referring to the drawing in detail 10 representsthe intake manifold ofan internal combustion engine, with which the lubricator forming thesubject matter of the present invention is adapted to be associated.

- This lubricator comprises 'a supply tank :11 which is provided with afilling opening in the top thereof and normally closed by a plug 12. Thesupply size and configuration,"and is adapted to be mounted upon thedash board 13 by suitable clamping bands 14. inthe position shown inFigure 1. Arranged centrally within the tank 11 is a hollow tubularmember 15 which reposes upon the bottom of the tank, and also extends anappreciable distance through .an opening in the top thereof asillustrated in Figure 2. Theupperend of this'tubular member is closed bya cap 16 which has associated therewith a valve body 17, in whichoperates a needle valve 18. Leading from the valve body 17 and coupledin any suittank .10 can vary m 1926. Serial NO: 128,211.

able manner with the intake manifold 10 is a lubricant supply pipe thelubricant is conveyed from the tank 11 to the motor when the latter isin operation, thereby maintaining the valves, valve guides and walls ofthe cylinder properly lubricated to increase the life and efficiency ofthe motor as a whole. The hollow tubular member 15 is adapted to receiveand support a felt roll 20, which is substantially coextensive 1n lengthwith the tubular member,

19, through which reposing upon the bottom of the tank 11,

but terminating a short distance from the upper end of the tubularmember, so that a cup-shaped screen 21 can be arranged within thetubular member directly above the roll 20 as shown. The lower edge ofthe tubular member 15 is notched as at'22 to provide passages throughwhich the oil or lubricant in the container 10 is allowed to pass inorder to saturate the felt roll 20.

Of course the oil is conveyed toward the upper end of the tubularmemberby capillary, action, and is removed from the roll 20 by the suctionpull of the motor. The tubular member 15 is provided with acircumferential series of vent openings 23, through which air is drawnby the suction of the motor, 20, and thereby carries the oil from theroll into the intake manifold 10 for the purpose above stated. Theinvention is ver simple in construction, and can be applie to any makeof automobile by simply providing an opening in the intake manifold ofthe engine for the reception of the supply pipe 19.

. While it is believed that going description, tages of the parent, Idesire to have it understood, that I do not limit myself to what isherein shown and described and that such'changes may be resorted to whendesired as fall within the scope of what is claimed.

'What is claimed is:

. 1. A lubricating device comprising a supply tank, a hollow tubularmember arranged centrally within the tank, a felt roll arranged withinthe tubular member and adapted to be maintained saturated with lubricantfrom said tank through openings in the tubular member adjacent the lowerend thereof, said tubular member projecting above said tank and having aplurality of vent openings, a cap closing the upper end from theforeinvention will be readily apthe nature and advanof the tubularmember, a supply pipe leading from the tubular member, and a valve insaid pipe and supported on said cap and controlling communicationbetween the pipe and said member.

'2. A lubricating.device,-comprising a supply tank, a hollow tubularmember arranged centrally within the tank and projecting through anopening in the top ofthe latter,

a felt roll arranged Within the tubular memher and adapted tobe'maintained saturated With-lubricant from the tank through openingsadjacent the lower end of the tubular ber, and a valve controllingcommunication 2 between the pipe and said member.

In testimony whereof I afiix my signature.

WILLIAM" 0.. EISENGART.
